We have a display case for a small collection of Tektronix CRTs, CRT components and memorabilia which spans the history of CRT development and production at Tektronix from start to finish.  Some of the CRTs on display include:

  • T51 (early version): a Tektronix replacement for an initially-used DuMont CRT. Starting in the mid-1950s, it was used in the Type 530 and 540 scopes, the 515, and the 570 and 575 curve tracers.
  • RCA 3WP1: used in the Type 310, 310A, 315D and 360 scopes. It was later made at Tektronix as the T310, also on display.
  • Three prototype CRTs Bob Anderson used to develop Tektronix' Direct View Storage Tube (DVST) technology (see photo at bottom of page).
  • T5640: an early sample obtained from Bob Anderson. A handwritten note on the screen, probably in Bob's handwriting, identifies the split line in the screen, allowing simultaneous examination of two stored traces.
  • T519: used in Type 519 scope, capable of DC to 1GHz bandwidth. Employed widely in nuclear weapons testing because its capability of capturing sub-nanosecond pulses.
  • T214: DVST version of the smallest CRT Tek made. Used in the Type 214 oscilloscope.
  • T2440: used in Model 2465 and several other portable scopes. Incorporated a revolutionary Tektronix designed meshless quadrupole scan expansion lens.
  • T4650: used in the Type 465 scope and several others, over a quarter of a million of these were produced during its lifetime.
  • T6110: Tek's first large (11") graphics DVST, uses the largest ceramic funnel Tek produced. Employed in the 400X monitors and the 4051 and 4052 desktop graphics systems.
  • T7100: microchannel plate CRT used in the 7104 1GHz scope. Probably the most complicated CRT Tektronix made.
  • T7612: an electron - bombarded semiconductor sensor used as the digitizer CRT in the 7612D instrument, capable of 200MSamples per second data capture.
  • T7630: a scope storage CRT with three meshes and bistable storage target capable four different storage modes: normal and fast bistable as well as normal and fast variable persistence. The CRT was used in Type 7623 and 7633 oscilloscopes.
  • T8250: Avionics color CRT used in the USAF C17 transport.
  • T8262: Avionics color CRT (envelope only, no gun) used in the B2 (Stealth) bomber.
  • Liquid Crystal Light Valve CRT: prototype projection CRT developed during the 1980's, capable of displaying full HD video. It employed a writing and erase gun used sequentially. This is perhaps the most peculiar ever produced although the design was never productized.
  • Scan expansion mesh from the T647 CRT.
  • Electron gun from the T2440 CRT.
  • Electron gun from the T555 CRT.
  • Writing and read guns from the 7912 CRT.
  • Samples of deflection plates.
  • Mugs and ceramic coaster from the 35th anniversary celebration of the CRT operation.


Many of the exhibits came from the CRT Time Capsule. We have some of the most unique CRTs and components ever produced, and all were made at Tektronix.


Here is a photo of Bob Anderson along with all the prototype CRTs used to develop the first Direct View Storage Tube (DVST) CRT.  The three prototype CRTs are in the upper right top shelf of the CRT exhibit.


Here are some photos of CRT manufacturing at the Sunset plant.
